Nasopharyngeal irradiation treatment of hyperplastic adenoids.
Radiotherapy treatment in childhood is an important cause of thyroid cancer. In the 1930 to 1950 era, radium irradiation of the nasopharynx was used to control hyperplastic adenoids. Because of the technical characteristics of this applicator, sufficient radiation was not applied to the thyroid by this technique to stimulate the development of thyroid malignancies. No malignancies have been reported thus far as a result of this treatment.
